In addition, the by-products of olive production also find many uses. Due to the specific climatic requirements of the olive tree, olives are primarily cultivated in Mediterranean countries. The olive tree is widely distributed across Turkey. The Aegean, Marmara, Mediterranean, and southeastern Anatolia regions are the leading olive-producing regions of Turkey. Similar to most olive-cultivating countries around the world, the majority （nearly 73%） of the olives produced in Turkey are processed into olive oil. The average annual production of olive oil in Turkey is 150,000 t. The leading olive-producing provinces in the southeastern Anatolia region are, in descending order of importance, Gaziantep, Kills, Sanllurfa, Mardin, Adlyaman, Slrnak, and Diyarbaklr.展开更多

It is expected that Asia will account for 12 of the world’s 25 cities with population exceeding 10 million by 2000. Tokyo will have more than 27 million people and Shanghai and Jakarta will each have more than 20 million people. Demand for water supply, as a result, will drastically increase. Data show that most of the East and Southeast Asian countries are faced with serious water shortage and contamination, in particular in the urbanized areas. The vulnerability of water supply constituents one of the greatest threats to the sustainable socio economic development of the region. Great efforts have been made to conserve both surface and subsurface water resources, to protect water from contamination and to use water in an efficient way. In addition to the establishment of administrative agencies under the governments in individual countries, a number of regional and country wide projects have been launched for a solution to ease the water vulnerability. The Coordinating Committee for Coastal and Offshore Geoscience Programmes in East and Southeast Asia (CCOP), an intergovernmental organization of the region, has devoted itself to coordinating regional endeavours to solve applied geoscientific problems through technology transfer, human resources development and regional data compilation. The regional map series and related databases produced by CCOP have provided useful information on regional geological background, which is also essential for the solution of water problems. However, it is obvious that regional efforts are not enough to meet the challenges we are faced with. In addition to raising public awareness and governmental concerns, advanced technologies, in particular those used in the petroleum industry to deal with oil and gas, a sort of fluid resources similar to water, must be adopted to the water supply industry. Since 1996, CCOP has, in cooperation with the developed countries, been working on a project called Petrowater. The Project aims at using the technology and infrastructures related to the oil industry to the water supply industry.展开更多

The hilly and mountainous terrain of this area, combined with rapid rainfall accumulation, has led to a surge in flash floods and severe geological hazards. On August 10, 2019, Typhoon Lekima made landfall in Zhejiang Province, China, and its torrential rainfall triggered extensive landslides, resulting in substantial damage and economic losses. Utilizing high-resolution satellite images, we compiled a landslide inventory of the affected area, which comprises a total of 2,774 rainfallinduced landslides over an area of 2965 km2. The majority of these landslides were small to mediumsized and exhibited elongated, clustered patterns. Some landslides displayed characteristics of high-level initiation, obstructing or partially blocking rivers, leading to the formation of debris dams. We used the inventory to analyze the distribution pattern of the landslides and their relationship with topographical, geological, and hydrological factors. The results showed that landslide abundance was closely related to elevation, slope angle, faults, and road density. The landslides were predominantly located in hilly and low mountainous areas, with elevations ranging from 150 to 300 m, slopes of 20 to 30 degrees, and a NE-SE aspect. Notably, we observed the highest Landslide Number Density(LND) and Landslide Area Percentage(LAP) in the rhyolite region. Landslides were concentrated within approximately 4 km on either side of fault zones, with their size and frequency negatively correlated with distances to faults, roads, and river systems. Furthermore, under the influence of typhoons, regions with denser vegetation cover exhibited higher landslide density, reaching maximum values in shrubland areas. In areas experiencing significantly increased concentrated rainfall, landslide density also showed a corresponding rise. In terms of spatial distribution, the rainfall-triggered landslides primarily occurred in the northeastern part of the study area, particularly in regions characterized by complex topography such as Shanzao Village in Yantan Town, Xixia Township, and Shangzhang Township. The research findings offer crucial data on the rainfallinduced landslides triggered by Typhoon Lekima, shedding light on their spatial distribution patterns. These findings provide valuable references for mitigating risks and planning reconstruction in typhoon-affected area.展开更多

A control experiment is performed with two runs driven by the mean ERA-40 data during 1958-1977 and 1981 2000, respectively. The model reproduces the major decadal-scale circulation changes in late spring over East Asia, including a cooling in the upper troposphere and an anomalous meridional cell. Accordingly, the precipitation decrease is also captured in the southeast of the upper-level cooling region. To quantify the role of the upper-level cooling in the drought mechanism, a sensitivity experiment is further conducted with the cooling imposed in the upper troposphere. It is demonstrated that the upper-level cooling can generate the anomalous meridional cell and consequently the drought to the southeast of the cooling center. Therefore, upper tropospheric cooling should have played a dominant role in the observed late spring drought over Southeast China in recent decades.展开更多

Not many researches have been focused on the positive side in form of opportunities presented due to climate change. The study aimed to show the climate change scenarios and explore possible opportunities that could be derived from such scenarios in the southeastern region of Zimbabwe. The research used climate data records from three Zimbabwe Meteorological Services Department run weather stations in the region. The time series data were analyzed to show trends of rainfall and temperature over time. A questionnaire survey was also carried out to enquire from the farmers if they perceived climate change to have any opportunities. The rainfall trend analysis showed that rainfall amounts have declined at two of the three stations used. Rainfall total was also shown to be variable from year to year at all the stations. Ambient temperatures at all the stations were shown to have increased for both winter and summer. Opportunities that could be derived from climate change in the region were identified as the hydrological, agricultural and industrial. The research concludes that taking advantages of opportunities offered by climate change and variability provides the quickest way of embracing climate change adaptation.展开更多
